Tether, the leading stablecoin issuer known for its USDT token, has expanded its Bitcoin reserves to approximately 150,000 BTC. CEO Paolo Ardoino announced the milestone at the Plan ₿ Forum in Lugano on November 3, 2026, estimating the company’s Bitcoin position at over $11.5 billion. The figure reflects a significant boost in Tether’s cryptocurrency exposure since the start of the year.
Tether pursues strategic Bitcoin acquisitions
The company’s sizable Bitcoin accumulation follows a policy introduced in May 2023, which mandates the allocation of 15% of Tether’s net profits each quarter toward Bitcoin purchases. This initiative is designed to diversify the company’s reserves while reinforcing its long-term commitment to the digital asset sector.
Under this policy, Tether conducted several major acquisitions. On December 31, 2025, the firm purchased 8,888 BTC for about $780 million, according to public records. The company continues to add to its Bitcoin position in 2026, although it does not publish the specifics of each transaction.
Tether’s profit allocation strategy directs a portion of quarterly earnings to regular Bitcoin purchases. This is part of a broader reserve management effort to strengthen its presence in the digital asset market.
US Treasury holdings anchor Tether’s reserves
While Bitcoin now represents a notable part of Tether’s assets, the company continues to maintain significant holdings in U.S. Treasury securities. These instruments remain the primary backing for USDT, ensuring liquidity and stability in day-to-day operations.
Tether’s third-quarter 2026 attestation revealed approximately $132.4 billion invested in U.S. Treasury securities, including repurchase agreements. The firm also reported excess reserves of $7.95 billion for the same period, nearly double the previous quarter’s figure. Excess reserves refer to funds that exceed what is required to redeem all circulating USDT tokens.
The assets in Tether’s balance sheet serve different purposes. While U.S. Treasuries secure the stablecoin liabilities, Bitcoin is acquired from profits and is held as a portfolio investment.
| Asset Type | Value (Q3 2026) | Purpose |
|---|---|---|
| U.S. Treasuries (+ Repos) | $132.4 billion | Backing USDT, ensuring liquidity |
| Bitcoin Holdings | 150,000 BTC ($11.5 billion) | Long-term investment, profit allocation |
| Excess Reserves | $7.95 billion | Buffer for stability, not tied to USDT |
Infrastructure investments advance mining integration
Tether is also expanding into Bitcoin mining infrastructure. On October 24, the company announced agreements with 15 mining companies, ASIC manufacturers, and mining pools to cooperate on its Mining Development Kit (MDK) initiative.
The MDK provides an open-source framework for integrating mining hardware and software through a unified infrastructure layer. Developers can use MDK to build monitoring systems and automation tools compatible with multiple devices and pools, reducing the need for bespoke integrations.
Industry fragmentation is a major challenge for Bitcoin mining. The MDK aims to address this by allowing participating firms to create “MDK Workers,” which link their technologies into one interface. This structure offers operators more control and flexibility in managing mining operations.
Tether has already deployed its QVAC mining agent within the MDK environment. This tool demonstrates how artificial intelligence applications can interact with mining infrastructure via the platform. The company expects to launch MDK version 1.0 by the end of 2026.
Mini dictionary: Mining Development Kit (MDK) – An open-source toolkit by Tether designed to create a standardized interface for Bitcoin mining hardware and software, enabling easier integration, monitoring, and automation across different vendors and pools.
Growing user base and exposure to volatility
Ardoino also reported that Tether now serves over 730 million customers worldwide, with around 30 million new wallets added each quarter. This rapid adoption strengthens its position in the global digital asset market, as USDT is widely used for on-chain transactions.
However, the expanding Bitcoin reserves introduce new risks. The value of Tether’s corporate assets will fluctuate with the market price of Bitcoin, exposing the company to potential volatility.
Tether acquires Bitcoin using profits, rather than funds backing USDT, containing risk to its investment portfolio if crypto prices decline. The company’s reported excess reserves provide an additional safeguard against market swings.
Tether’s initiative to unify mining infrastructure through its MDK project could have lasting impacts on the Bitcoin mining ecosystem, bringing together pools, hardware manufacturers, and miners under one technological standard.
